Abstract
Background: None of the current therapeutic approaches for management of Graves' disease has been able to re-establish normal thyroid function in all patients. Objective: To describe the author's 35 years of personal experience in the management of Graves' hyperthyroidism and, in doing so, review current articles published on the long-term medical treatment of hyperthyroidism. Methods: All published articles related to ≥4 years of continuous antithyroid drug (ATD) treatment were searched. Findings were added and compared with studies published by the authors on the same topic. Results: Long-term ATD treatment is effective and safe, both in children and adults, for treatment of hyperthyroidism. Treatment of Graves' patients with ATDs >60 months causes euthyroidism up to 4 years after discontinuation of ATDs in the majority of patients. Long-term ATD therapy is not inferior to radioiodine therapy and may sometimes even be superior in some aspects, when considering serum lipid profile, cardiac function, mood, and cognition. Conclusions: Long-term ATD therapy for Graves' hyperthyroidism is efficient and safe and induces control of hyperthyroidism, without rendering the patient hypothyroid in the majority of patients.
